I found this article and I thought it was interesting for people with spine problems. I was started on Sulfasalazine for my Auto-immune problem.
I soon found out it helped my sciatica pain.
So I did some research and found TNF's have worked to help sciatica pain. I know Sulfa isn't a TNF but a DMARD. However, I think researchers are on to something.
Below is a link. I asked my Rheumy and PM if a TNF drug would help me. They both said yes but you would never get insurance to help pay under that classification.
Regardless, If the pro's think it helps it will only be a matter of time before us spine people have another option.
